Hi David. I've recently thrown myself in the deep end myself so am probably well equipped to give you a quick run down on things a newbi should know.
Probably best to email me directly as well as putting some details on this thread: [email protected]

Firstly the salaries are good compared to the UK, the downside is some of the expenses you will incur.
Based on the fact that all you will have is what you can carry in your suitcase then you will need to spend a bit of cash kitting yourself out with the essentials.
Accommodation here is expensive unless you share with other guys which is common and the norm.
Are you bringing family or kids?
